CLIMATE SCIENCE SPECIAL REPORT (CSSR)
Final Clearance 28 June 2017 

Donald Trump versucht zwar die US Ministerien und Behörden zu -->zensieren
und macht einen privaten -->Propagandakanal in seinem Wolkenkratzer auf,
aber das ändert nichts an der wissenschaftlichen Realität.

Der übliche US Bericht CSSR wurde noch nicht publiziert,
aber geleakt, und es steht das übliche drin (nur genauer als früher):
der Klimawandel hat viele messbare Auswirkungen,
er ist menschengemacht und langfristig in Summe 
extrem teuer und schädlich (Wetterextreme, Wasserknappheit
und Überschwemmungen (wärmere Luft kann mehr Wasser 
halten, und wenn sie dann gesättigt ist, regnet es im mittel mehr),
Verschiebung und Zerstörung von Vegetationszonen mit
einhergehendem Artensterben, abnehmende Getreideernten, 
Anstieg des Meeresspiegels (alle Häfen und globaler Handel betroffen) ...
und das CO2 verursachte bereits eine messbare Ozeanversauerung, ..

State of the Climate in 2016 (300 Seiten)

"In 2016, the dominant greenhouse gases released into Earth’s atmosphere—carbon dioxide, methane, and nitrous oxide— continued to increase and reach new record highs. The 3.5 ± 0.1 ppm rise in global annual mean carbon dioxide from 2015 to 2016 was the largest annual increase observed in the 58- year measurement record. The annual global average carbon dioxide concentration at Earth’s surface surpassed 400 ppm (402.9 ± 0.1 ppm) for the first time in the modern atmospheric measurement record and in ice core records dating back as far as 800000 years.

One of the strongest El Niño events since at least 1950 dis- sipated in spring, and a weak La Niña evolved later in the year. Owing at least in part to the combination of El Niño conditions early in the year and a long-term upward trend, Earth’s surface observed record warmth for a third consecutive year, albeit by a much slimmer margin than by which that record was set in 2015. Above Earth’s surface, the annual lower troposphere temperature was record high according to all datasets analyzed, while the lower stratospheric temperature was record low according to most of the in situ and satellite datasets.

Several countries, including Mexico and India, reported record high annual temperatures while many others observed near-record highs. A week-long heat wave at the end of April over the northern and eastern Indian peninsula, with tempera- tures surpassing 44°C, contributed to a water crisis for 330 million people and to 300 fatalities.

Pesticides could wipe out bumblebee populations, study shows

Neonicotinoid drastically cuts egg-laying by queens, affecting their ability to start new colonies and increasing chances of local extinction, say scientists

It’s Not Your Imagination. Summers Are Getting Hotter.

Extraordinarily hot summers — the kind that were virtually unheard-of in the 1950s — have become commonplace.

This year’s scorching summer events, like heat waves rolling through southern Europe and temperatures nearing 130 degrees Fahrenheit in Pakistan, are part of this broader trend.

The chart (..), based on data from James Hansen, a retired NASA climate scientist and professor at Columbia University, shows how summer temperatures have shifted toward more extreme heat over the past several decades.

This guide that seeks to explain the treatment of land use under the United Nations Framework Convention on Climate Change (UNFCCC), including requirements for reporting GHG emissions and removals, accounting under the Kyoto Protocol, and guidance for REDD+.

Background:
While greenhouse gas emissions from land use have the same warming effect on the atmosphere as other emissions, land use is different from other sectors in a number of ways. As a consequence, reporting and accounting of emissions from land use has developed under the United National Framework Convention for Climate Change (UNFCCC) differently to other sectors. It has come to be seen as an arcane and complex subject, even for those who work on climate and forest issues.

The objective of Understanding Land Use in the UNFCCC is to increase understanding of how human induced emissions and removals from the land sector are reported and accounted for within the UNFCCC. This Summary for Policymakers provides a high level summary of the Guide.

Land is an essential building block of civilization yet its contribution to our quality of life is perceived and valued in starkly different and often incompatible ways. Conflicts about land use are intensifying in many countries. The world has reached a point where we must reconcile these differences and rethink the way in which we use and manage the land.

The evidence presented in this first edition of the Global Land Outlook demonstrates that informed and responsible decision-making, along with simple changes in our everyday lives, can if widely adopted help to reverse the current worrying trends in the state of our land resources.

UN Food and Agriculture Organization:
Report: State of Food Security and Nutrition in the World 2017

World hunger again on the rise, driven by conflict and climate change, new UN report says
815 million people now hungry – Millions of children at risk from malnutrition

15 September 2017, Rome - After steadily declining for over a decade, global hunger is on the rise again, affecting 815 million people in 2016, or 11 per cent of the global population, says a new edition of the annual United Nations report on world food security and nutrition released today. At the same time, multiple forms of malnutrition are threatening the health of millions worldwide.

The increase - 38 million more people than the previous year - is largely due to the proliferation of violent conflicts and climate-related shocks, according to The State of Food Security and Nutrition in the World 2017 (PDF).

The sixth mass extinction of global wildlife already under way is seriously threatening the world’s food supplies, according to experts.

“Huge proportions of the plant and animal species that form the foundation of our food supply are just as endangered [as wildlife] and are getting almost no attention,” said Ann Tutwiler, director general of Bioversity International, a research group that published a new report on Tuesday.

This year, the theme of the report is “Leveraging food systems for inclusive rural transformation”.

The new report looks at how population growth, increasing urbanization, technologies, and climate change are transforming rural and urban areas, and how the world’s food systems are evolving. The report concludes that fulfilling the 2030 Agenda depends crucially on progress in rural areas, which is where most of the poor and hungry live today, and outlines a strategy for how agriculture and rural economies in developing countries can provide prosperity.
